Abstract des Autors
Although mouthguards have been found to reduce injury, many athletes choose not to use them because of the belief of negative effects on breathing with mouthguard use. Therefore, this study investigated the effects of mouthguard use on physiological variables in women using a self-adapted mouthguard made for women and a universal self-adapted mouthguard. Eleven subjects (mean ± SD; age: 22 ± 3.3 y; height: 159.8 ± 4.3 cm; body mass: 63.7 ± 8.9 kg) performed 3 separate maximal cycle ergometer tests with either 1 mouthguard or no mouthguard. Heart rate (HR), rating of perceived exertion (RPE), oxygen consumption ([latin capital V with dot above]O2), minute ventilation ([latin capital V with dot above]E), and respiratory exchange ratio (RER) were measured at each exercise intensity and at the end of each test. HR, RPE, and [latin capital V with dot above]O2 increased for each mouthguard condition across power levels. [latin capital V with dot above]E and RER increased more from 110W to max with the no mouthguard condition than for either mouthguard. However, there was no significant difference in [latin capital V with dot above]E or RER at any given power level between mouthguard conditions. The results indicated mouthguard use did not affect HR, RPE, [latin capital V with dot above]E, [latin capital V with dot above]O2, or RER at any given power level during exercise, including the guard made specifically for women. Therefore, athletes are encouraged to use mouthguards without fear of negative aerobic performance effects. Verf.-Referat
